As soon as you have connected power to the modem, if you are an experienced modem user, you may simply want to check your modem’s settings for data compression, error correction, and so on. You may find that you can get moving quite quickly if you just issue an ATL5, ATL6 and an ATL7 command.

    MT2834BLR Owner’s Manual 3.5.1 How Can You Identify Your UART Type? If you have MS-DOS 6.0 or later, you can find your UART type from a diagnostic program called MSD. To use it, type MSD at the DOS prompt. After the opening screen, select COM Ports..The last line of the report tells you what type UART you have for each COM port.

  • Page 25: Configuring Your Software

    Chapter 3 - Software Configuration Configuring Your Software Communications software must be configured to work with your modem, your computer, and the remote system it is calling. Fortunately, most communications programs make the process easy by providing a default initialization string for your modem as well as defaults for most of the other required parameters.

  • Page 26: Pc Initialization Strings

    MT2834BLR Owner’s Manual PC Initialization Strings We recommend the following initialization string for a MultiModem connected to a PC-compatible computer when sharing a line with a telephone: AT &F X4 S0=0 ^M This string resets the modem to the factory default settings, selects extended result codes with NO DIAL TONE and BUSY, and turns off auto-answer.

  • Page 27: Macintosh Initialization

    Chapter 3 - Software Configuration Macintosh Initialization Macintosh computers cannot use RTS/CTS hardware flow control without a serial cable wired for hardware control. The Macintosh 128 and 512 models cannot use RTS/CTS flow control at all. For those Macintoshes turn off the default RTS/CTS hardware flow control, turn on XON/XOFF flow control and pacing, and ignore DTR: AT &F X4 &E5 &E13 &D0 ^M For hardware flow control, use the following initialization string:...

  • Page 28: Configuring Software For Your Computer

    MT2834BLR Owner’s Manual Configuring Software for Your Computer You must configure your communications software to match your computer’s configuration. If the modem is connected to the COM2 serial port, you must tell the software you are using COM2. Another important parameter is the serial port baud rate. This is the speed at which your modem communicates with your computer, not the speed at which your modem communicates with another modem.

  • Page 29: When To Disable Data Compression

    Chapter 3 - Software Configuration 3.10 When to Disable Data Compression If your serial port cannot keep up because it has an older UART, you may lose data when using data compression. Also, the speed advantage hardware compression gives you is entirely dependent on how much the data being transmitted can be compressed.

  • Page 30: Using At Commands

    MT2834BLR Owner’s Manual 3.11 Using AT Commands You control your modem by issuing AT commands, setting S-Registers, and setting DIP-Switches. You can easily change the settings of your DIP-Switches, as they are located on the right side of your modem’s chassis. Right now your modem is set up for the most typical user application, that is, as a traditional modem set to make a dial-up call to a remote installation where the call is answered automatically;...

  • Page 52: Introduction

    MT2834BLR Owner’s Manual Introduction Each time you power up the modem, it performs an automatic self- test to ensure proper operation. The modem also has four diagnostic test features: Local Analog Loopback, Digital Loopback (remote/ automatic), Digital Loopback (local/manual) and a modem Back-to-Back test. A loopback test involves entering data from your PC and looping that data through the circuits of your modem and/or a remote modem.

  • Page 53: Local Analog Loopback Test/V.54 Loop 3

    Chapter 5 -Testing Your Modem Local Analog Loopback Test/V.54 Loop 3 In this test, data from your computer or terminal is sent to your modem's transmitter, converted into analog form, looped back to the receiver, converted into digital form and then received back at your monitor for verification.

  • Page 54: Digital Loopback Test/V.54 Loop 2 (Local/Manual)

    MT2834BLR Owner’s Manual Digital Loopback Test/V.54 Loop 2 (Local/Manual) In this test, your modem must be On-Line with another modem that can respond to a request for Digital Loopback, such as another MT2834BLR. The Digital Loopback Test is an on-line test that loops data sent from one modem across the phone line to another modem, then back to the first modem.

  • Page 55: Digital Loopback Test/V.54 Loop 2 (Remote/Automatic)

    Chapter 5 -Testing Your Modem Digital Loopback Test/V.54 Loop 2 (Remote/Automatic) In this test, your modem must be On-line with another modem set up to respond to a request for Digital Loopback, such as another MT2834BLR. With the MT2834BLR, this ability to respond is controlled by the &T command.

  • Page 56: Synchronous Mode Testing

    MT2834BLR Owner’s Manual Synchronous Mode Testing The following tests must be run with your modem in Synchronous mode (DIP Switch #12 in the Up (OPEN) position), DIP Switch #9 controls the modem’s Synchronous mode testing function. (Refer to Chapter 9 for DIP Switch information.) The test procedures for Synchronous mode are different from those for Asynchronous mode.

  • Page 57: Digital Loopback Test (Local/Manual) (Synchronous Mode)

    Chapter 5 -Testing Your Modem Digital Loopback Test (Local/Manual) (Synchronous Mode) This test must be run when you have a data connection with another modem. If a Local Analog Loopback Test resulted in errors, and this test passes without errors, then the problem exists in your computer-to-modem connection.

  • Page 58: Digital Loopback Test (Remote/Automatic) (Synchronous Mode)

    MT2834BLR Owner’s Manual Digital Loopback Test (Remote/Automatic) (Synchronous Mode) This test must be run when you have a data connection with another modem. In this test, data is passed to the remote modem and is looped back to the local modem (as if an ATU2 command was issued in Asynchronous test mode), as shown in Figure 5-6.
